Core-js is a modular standard library for JavaScript that polyfills ECMAScript features not present in older browsers. It provides a set of polyfills for features like Promises, Symbols, Iterators, and more, ensuring compatibility across different environments. Core-js allows developers to write modern JavaScript code without worrying about browser support, making it easier to leverage the latest language features.
Compared to other polyfill libraries, Core-js offers a comprehensive solution with a wide range of polyfills and a modular approach that allows you to include only the necessary features. It is actively maintained and regularly updated to support new ECMAScript standards and browser requirements.
